When a power source (eg. a battery, a generator etc.) is used to provide electrical power to a load, the system (power source, wiring, switches etc) are designed to carry a certain amount of power, which is dependent on the current in the circuit. (The “load” can be a lamp, motor, TV set, oven etc.) […]
The Efficiency of an induction motor defined as the ratio between output power and input power. Induction motor is electrical energy to mechanical energy converter so the input power is nothing but electrical power which is the product of voltage and current but output power is mechanical power which is the product of torque and shaft speed. The output power […]
Imagine that you start with no charge in the capacitor in question and then connect it to some kind of source. For the purpose of argument, lets suggest that it is a battery and the current is flowing through a resistor. At the instant the battery is connected, the capacitor has no charge on it […]
Compressed air systems are a major utility area in the process industry and consume up to 20-30% of energy in the plant. In the current Situation, the compressed air cost is around Rs 1-3 CFM which is pricey. 80% of Industries use screw compressors. Screw compressors due to their unloading consumption patterns cause a loss of […]
Indirect costs eating away at your wallet? Here are seven ways that we have found to be effective in increasing profits, lowering unit prices for your customers whilst continuing to make them happy – Simplifying your product or streamlining your product. Using lean manufacturing initiatives. Introducing preventive maintenance. Embracing Industry 4.0 technology. Reviewing labor costs and manufacturing overhead. Recycling […]
Low power factor in a system arises from unavoidable inductive loads consisting of lighting fixtures, motors, transformers, electromagnets etc. The way to improve power factor and go for better utilization of generation and distribution facilities involves the following— Use of more efficient motors with high power factor. Select optimum sizes of equipment/ motors. They have […]
By installing suitably sized switched capacitors into the power distribution circuit, the Power Factor is improved and the value becomes nearer to 1 thus minimising wasted energy, improving the efficiency of a plant, liberating more kW from the available supply and saving you money!The purchase cost of the installation is usually repaid in less than […]
Increased system capacity and reduced system losses in your electrical system By adding capacitors (KVAr generators) to the system, the power factor is improved and the KW capacity of the system is increased.Uncorrected power factor causes power system losses in your distribution system.By improving your power factor, these losses can be reduced.With the current rise […]
(Note that all these issues result in a change of reactive/ real power) Inductive loading – 90% of the industrial load consists of induction machines (single and three phase). Such machines draw magnetizing current to produce the magnetic field and hence work at low power factor. Variations in power loading – When the system is […]
Higher current is required by the equipment, due to which the economic cost of the equipment is increased. At low power factor, the current is high which gives rise to high copper losses in the system and therefore the efficiency of the system is reduced. In Points Cross section of conductor increases: As power factor […]
